Wind/solar don't produce baseload power absent storage. If you can't scale storage proportionately to wind/solar, you can't compare w/s to nuclear because baseload and non-baseload supply are not mutually substitutable.
Battery capacity will be a minor constraint, but only minor, as there are constraints in the PV and wind turbine supply chains as well.
Those constraints are primarily NIMBY, the consenting processes for mines, refineries, and assembly factories in the case of PV and batteries, and for deployment in the case of wind.
NIMBY applies ten-fold to nuclear.
- overbuild renewables
- connect grids together
If regional grids are connected together, then excess capacity in one region can be used by another. You don’t have to store your own electricity for later if you your neighbour can sell you their excess.
Wind being unable to work in to winter is an assertion that will need some backing up.
Unimaginably expensive is not accurate description. A) hydro is an already existing solution that can work as storage. B) HVDC lines are unimaginably expensive compared to what? Nuclear, while dependable is not exactly cheap either.
